To see a vat in your dreams, foretells anguish and suffering from the hands of cruel persons, into which you have unwittingly fallen.
A vat seen in a dream is an ill omen but must also be taken in context of the entire dream and correlated. This can foretell sorrow, grief, cruel friends, an unfaithful lover, etc..
If you dream you see or are carrying a full tank, it portends getting a good income if the tank is empty - do not expect a good income.
